THIS MANUAL WILL DESCRIBE THREE WAYS TO CAPTURE A PASSIVE
SAMPLE. FIRST WE WILL DESCRIBE HOW TO COLLECT A PASSIVE SAMPLE
OVER AN OPEN CONTAINER. SECOND. WE WILL DESCRIBE HOW THE
INSTRUMENT IS DESIGNED TO AUTOMATICALLY COLLECT A SAMPLE OF
AIR FROM A SUSPECT WHO IS BLOWING IN THE DIRECTION OF THE
INSTRUMENT; AND FINALLY WE WILL DESCRIBE HOW TO COLLECT A
PASSIVE AMBIENT AIR SAMPLE FROM THE VICINITY OF A SUSPECTED

The drink sniffer adapter allows the inlet port of the Alco-Sensor FST to extend
beyond the body of the instrument and provide better access for sampling the
alcohol vapor that sits just above the liquid in a glass. Proper use of the 'drink
sniffer' adapter will increase the sensitivity of the Alco-Sensor FST when testing the
gas (or headspace) above the surface of a liquid.
The ASFST, with the drink sniffer attached, should be positioned within one or two
inches above the surface of the liquid.

The best method to passively test a subject with the Alco-Sensor FST is to
automatically capture a sample from a subject who blows at the Passive Sampling
Cup. To accomplish this, the instrument must have a Passive Sampling Cup
attached and be in the Passive Mode with "
